IMPROVEMENT IN DEVICES FOR COLLECTING AND SAVING THE PARTICLES 0F SUGARRISING WITH THE STEAM FROM VACUUM-PANS.

Specification forming part of Letters Patent N o. I 91,537, dated June5, 1877; application filed March 15, 1877.

To all whom it may concern:

Be it known that we, FRANZ O. MATTHIES- SEN, of Irvington, New York, andAUGUsTE A. GOUBERT, of the city and State of New York, have invented anImprovement in Vacuum-Pans, of which the following is a specification:

Our improvement relates to that class of vacuum-pans which are providedwith a goose neck or chamber extending laterally from the upper part ofthe pan; and the object of our improvement is to prevent the loss of thesugar-liquor which boils over from the vacuum-pan.

Our invention consists in erecting in the goose-neck two or more seriesof narrow def] etors, arranged in vertical planes across the go se-neck.

Our invention includes a peculiar formation of .46 deflectors, whichconsists in providing them with inwardly-curved edges, as and for thepurpose hereinafter described.

The deflectors arranged in the goose-neck present surfaces against whichfine particles or drops of sugar-liquor thrown from the vacuum-pan areprojected, while the steam rebounds from the deflectors, and makes itsway onward through the spaces between the deflectors. The drops ofsugar-liquor adhere slightly to the surfaces of the deflectors, and,under the influence of their own gravity, fall to the bottom of thegoose-neck, and from thence run back into the sugar-liquor in thevacuum-pan.

The accompanying drawings are as follows:

Figure 1 is a central vertical section of a vacuum-pan, and a portion ofthe goose'neck. Fig. 2 is a horizontal section through the line a: a; onFig. 1. Fig. 3 is a transverse vertical section of the goose-neck, andthe upper portion of the neck of the vacuum-pan, through the line 3 g onFig. 2.

No means for heating the vacuum-pan are shown, as steam-pipes and otherdevices for 4 that purpose are well known and in common use.

The drawings represent a vacuum-pan, A, of ordinary form, with its necka joined to the lateral chamber or goose-neck B. Ar-

ranged in parallel vertical planes across the goose-neck are two seriesof y-shaped deflectors, c and c. It will be seen that the second seriesof deflectors c are arranged immediately behind the spaces between thefront series of deflectors c. It will also be observed that the edges ofthe deflectors are curved inwardly, as shown in section in Fig. 2.

The deflectors may be made of wood, sheet metal, or any other suitablematerial. At their lower ends they should be in close contact with theshell of the goose-neck, to enable them to act efficiently in conductingto the shell of the goose neck the sugar liquor which collects uponthem.

Behind the second series of deflectors 0 there is erected, across thebottom of the gooseneck, the vertical wall D, the object of which is tohold back any sugar-liquor which may fall to the bottom of thegoose-neck, and which might otherwise run along the bottom of thegoose-neck toward the condenser.

The deflectors, instead of standing vertically, may be set diagonallyacross the gooseneck, one above another. In this case, instead of beingV-shaped, the deflector is a flat strip, set with its upper edgeinclined toward the neck of the vacuum-pan, and having its lower edgecurved upward, to form a trough or gutter for carrying to the side ofthe goose-neck drops of sugar-liquor caught by the deflector. A part ofone such deflector is shown in Fig. 1, in which E is the upper end ofthe deflector, where it is bolted to the shell of the gooseneck, and cis asection of it where it is cut by the section-line of the'drawing.This alternative mode of arranging the deflectors is also indicated indotted lines in Fig. 3.

In operation, drops or fine particles of sugarliquor carried along inthe current of steam from the vacuum-pan are caught upon the faces ofthe deflectors, and run down the deflectors by their own gravity intothe bottom of the goose-neck, and from thence back into the vacuum-pan,while the steam makes its way onward through the interstices between thedeflectors.

We claim as our invention 1. In combination with the goose-neck of avacuum-pan, two or more series of deflectors, tom of the goose-neck, andthus preventing each of such deflectors having one or both of suchliquor from flowing away from the vacits edges curved, as shown, to formtroughs uum-pan.
